I just got a new glasses to replace my old one. This new one got some problem.
1. It only looks clear and sharp on the top and bottom area. When I keep my head level, it is not clear. I have to view through the top (near the top frame) for it to look clear.
2. When looking thru the glasses with my head level, it looks like there is double-vision, or ghosting. Even when covering one eye.
